I did not have two different keys configured, if you look at my
configuration, i have configured Key 1 on R1 and Key 2 on R2 and the
passwords are identical, and i am showing that the higher key number
receives and processes the routes, whereas, the router with a lower Key
number does NOT.
In RIPv2, if you want both routers to exchange and process routes, and you
need MD5 authentication, the key numbers *MUST* match or else the routers
will not exchange routes. I was only showing the weird behavior because of
Petr's assumption of my configuration. I just wanted to show that there are
many behavioral issues in an IOS that is so flexible.
